An excuse, as if one were needed, to re-team Diane Keaton, Jane Fonda, Candice Bergen, and Mary Steenburgen, Book Club: The Next Chapter, while being a fairly traditional followup, is a very strange movie. By which I mean it really isn't a movie, but rather an opportunity to merely spend a cozy period in the dark watching four Hollywood legends of a certain age hang out in Italy and engage in sightseeing, slapstick, fashion parades, and the guzzling of liquor by the quart.
